Let's divide 87758971 by 81
Let's see how many times 81 fits into 87758971.

Advancing to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 81

Step 2:
81 goes into 87 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 81 away from 87, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 81

Moving on to step 3:
If we divide 67 by 81, we get 0 and a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 81

Step 4:
81 goes into 675 8 times with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtracting 648 from 675 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 81

Moving on to step 5:
81 can be fit into 278 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 1083.0
Subtracting 243 from 278 leaves us with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 81

Moving on to step 6:
If we divide 359 by 81, we get 4 and a remainder of 35.
The next digit of our result is 4. 
Result so far: 10834.0
Deduct 324 from 359 and we're left with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 81

Going ahead to step 7:
81 can be fit into 357 4 times, resulting in a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 108344.0
Deduct 324 from 357 and we're left with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 81

Advancing to step 8:
The number 81 fits into 331 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1083444.0
If we subtract 324 from 331, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 81, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 1083444.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
81 goes into 700 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1083444.08
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
If we divide 520 by 81, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1083444.086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
340 divided by 81 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1083444.0864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 1083444.08641
If we take 81 away from 160, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
81 goes into 790 9 times with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 1083444.086419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 15:
610 divided by 81 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1083444.0864197
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 16:
When dividing 430 by 81, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1083444.08641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 1083444.08641975 with a remainder of 2.5e-08.
